Check procedure:
Tension value: 34.6 N {3.53 kgf} Timing belt θ tension adjustment value
Adjust to obtain a deflection of 1.2 mm when the center of the belt is pushed with a force of 2.2 N {220 gf}
using a spring balance.
Center-to-center distance 78
Adjustment procedure:
Loosen screws (a) at four places and adjust tension in the belt with screw (b). After the adjustment, tighten
nut (c) and bond hexagon cap nut (d) with Loctite 242.

Check procedure:
When the Z-slide shaft is rotated about 360 degrees, the diffuser should not contact the nozzle outer surface.
(LAIC head only)
Turn the Z-slide shaft 360 degrees and check that the φ22.5-hole in the diffuser is not in contact with the
nozzle outer surface.
Adjustment procedure:
Temporarily secure the diffuser support to head bracket IC with SEMS cap (a). Using SEMS cap (b), install
the raxa paper base assembly to sandwich the diffuser. At this time, adjust the position of the diffuser
support to allow no clearance between the raxa paper base assembly and the bottom surface of FMLA; then
secure it in position. (See the illustration below.)
Adjust the position of the diffuser so that it does not contact the nozzle outer surface; then, secure it in
position. At this time, align the end face of the raxa paper base assembly with that of FMLA so that VCS
will not pick up the image of the bottom surface of FMLA. (See the illustration below.)
